Joe,
Sounds as if you already have everything pretty well under control. I have ONE credit card that I use for almost everything and then pay it off at the end of the month. Just one check to keep track of and I have a list of everything I have bought. My last 4 or 5 cars I paid cash for. Paid cash when I built my house and have stayed pretty much out of debt most of my life. A very good feeling now that I see houses all around me foreclosed on and people leaving. Keep up the good work and good luck.
Ron
